ROLLS FORCORN-PREPARING MACHINES.

SPECIFICATION forming part of Letters Patent N 0. 729,698, dated June 2, 1963. V

Application filed'May 2331902. erialNo.108,627. (No model.) l

To all whom it may concozq'rm DEN, a citizen oftheUnited states, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and usefullmprovements in Rolls for Corn- Preparing Machines," of which the following is a specification. I a

My present invention relates to that class of machines for preparing or treating corn in the stalk commonly denominated f corn huskers and shredders; and-itconsists in certain improvements in the rolls of'suchmachinem known as the husking-rolls and the snapping-rolls, said invention being applicable to both these two sets of rolls or to other rolls of like design and similar purpose.

Referring to the accompanying drawings, which are made a part hereof and on which similar reference characters indicate sgnilar parts, Figure 1 is a longitudinal vertic sectional view of so much of a corn-husking and fodder-shredding machine as illustrates -'the location and arrangement of theseveral rolls therein adapted to be constructed in accord-J ance with my invention and the adjacent and cooperating parts; Fig. 2, a top or plan View of the husking-rolls in said machine and immediately adjacent partswhen said-rolls are constructed in accordance with my present invention; Fig. 3, a transversesectional view of one pair of said rolls, showing my preferred construction thereof; Fig. 4, a perspective view of a fragment of one of said rolls,and Fig. 5 a perspective view of oneof the graspingteeth and also of one ofthe spacers which are inserted between the adjacent teeth in assembling the roll.

In said drawings the portions marked A represent the framework of a machine of a character suitable to embody my invention; 13 and C, the feeding-belts D, the shreddingcylinder; E, the shredding-concave, and F and G off-bearing conveyors. These parts, however, not being of my present invention are shown merely for purposes o-fillustration and will not, therefore, be further described herein except incidentally in describing the invention.

Generally speaking, my improvement consists in forming the otherwise cylindrical rolls with spirally-disposed longitudinal grooves inltlieir faces andplacin g within said grooves Be it known that I, WILLIAM R. TEEGUAR- the grasping-teeth, which engage with the stalks of-corn in the case of snapping-rolls or withthe husks on the ears in the case of husking-rolls. These rolls are so positioned in use that the groovescontaining the teeth in each pair of rolls register with each other, so that thetwo grooves are effectiveat the same point at substantially the same moment, while be and preferably are constructed in accord ance with my present invention. Each of said jrolls, as shown, has a longitudinal groove extending in a spiral direction from end to end thereof along its surface, and in these grooves are placed teeth 10. These teeth may be of any desired construction and secured in place in any desired manner. I have shown the bottom of the groove widened and the teeth pro- :vided with bases 11, fitting into the ,bottom portion of the groove and held at the proper distance apart by spacing-blocks 12,

widened similar in form tothe bases of the teeth, and

)this Iconsider a desirable construction; but any other form of these parts and means for securing them in place may be adopted which may be desired without departing from my invention. 1

, As above-stated, the groovesin each of the pairs' 'jof rolls are arranged to register with each other... This has the eifectof greatly increasing the grasping capability of the rolls as they revolve. Just before the cooperating parts of the grooves reach the position directly facing each other, as shown in the transverse section, Fig. 3, theymay be said to constitute a single grasping or biting groove composed of L the upper side of one groove and the lower side of the other, which is adapted to seize upon the portions of the cornstalks which may be presented I thereto and grasp therntightly and draw them through the rolls when ordinary smooth-surfaced rolls would slip over the large hard portions of the stalks presented thereto without grasping them, whereas my rolls are capable of receiving stalks of irregular shapes or of unusually large growth. The remaining porv tions of the surfaces of the rolls being suitably roughened, this especialy in the case of the snapping-rolls, has a tendency to crush the cornstalks, and thus better prepare them for the action of the shredding cylinder and concave. In all cases the result is to more certainly and rapidly feed the material through between the rolls, as the grasp in question is prompt and certain.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination, in a corn-preparing machine, of a pair of rolls geared to revolve in opposite directions toward each other, and each provided with a spiral groove in its surface running in the opposite direction from the groove in the other, said grooves registering with each other, whereby a continuously grasping or biting groove formed of the opposite sides of the grooves in the said two rolls is provided, and teeth seated in the grooves in each of said rolls and projecting into the corresponding grooves in the opposing rolls, substantially as set forth. In witness whereof I have hereunto set my hand and seal at Indianapolis, Indiana, this 19th day of May, A. D. 1902.
